Extra crankcase breather?

[ssray]

I did search-honest but i got bored after 18 pages.
The trx that was in pb had an extra crankcase breather, is it worth doing and how do i do it?

Me thinks it´s worth it if going past 8-8.5 k revs...
Never thought of it before with the TRX....but as i have a tuned 900 enjun in now with 6 gears and 16/42....
Easiest to check if any gains is to make a filter wich keeps oil in and let´s air out on the refill cap!
